  Objective Prenatal diagnosis of total anomalous pulmonary venous connection (TAPVC) is challenging even for experts.We sought to explore whether the use of spatiotemporal image correlation (STIC) can supply additional information with respect to conventional fetal echocardiography in the prenatal diagnosis of TAPVC.Methods Twenty-two cases diagnosed as TAPVC received fetal echocardiography examination from April 2009 to December 2013.Four-dimensional volumes from 16 cases of suspected TAPVC by conventional echocardiography at our hospital.Echocardiographic characteristics were compared with the results of postnatal work-up and pathology.Results Prenatal diagnosis was made at a mean gestational age of 26.6 (range 21 to 36) weeks.TAPVC was found in 22 cases by fetal echocardiography; four cases were isolated TAPVC, eighteen TAPVC had associated cardiac anomalies.Among them, nine cases were supracardiac types, five cases were infracardiac types and eight cases were intracardiac types.Twelve true positive cases of TAPVC were confirmed after birth or pathology.The fetal echocardiographic characteristics of 22 fetuses with TAPVC included absent insertions of pulmonary veins in the LA, increased distance between left atrium (LA) and descending aorta, presence of a confluence behind the left atrium, increased angle between left and right pulmonary veins.4D ultrasound with STIC clearly visualized the anomalous PV confluence and/or the draining vertical vein in all sixteen cases examined.Conclusion There are fetal echocardiographic characteristics of TAPVC.Conventional fetal echocardiography plays an important role in prenatal diagnosis of TAPVC.4D ultrasound with STIC should be proposed to identify abnormal venous drainage at the screening level, thus supplying additional information over that provided by 2D fetal echocardiography.

案例教学法又称苏格拉底式教学法[1],是英美法系国家如美国和加拿大等国法学院最主要的教学方法,于1870年前后最早使用于哈佛大学的法学教育之中。学生学习法律和法律原则,不是通过死记硬背具体的法律条文,而且是通过学习、研究大量的案例来掌握法律的精神和基本原则。这点和药理学相类似,在学生还未进入临床工作时,药物的药理作用、临床应用等学生也是死记硬背的,所以案例教学法在实践性和运用性较强的学科中普遍的运
